The Bloch "TapFlex" is a full leather split-sole tap shoe that features the exclusive Bloch 'sling technique' - allowing the shoe to bend in one direction and resist in another. Shoe also features a wick away lining for reduced moisture and comfort and a heel notch to alleviate pressure on the Achilles. This lace-up style is perfect for any dancer from student to professional. Fitting information: Growing kids, go up 1 size; sizes 2 - 3.5 are not made in this style so start up 2 sizes. All others, use street shoe sizing.
